MPROVEMENT IN IRON-PLANERS.

The Schedule referred to in these Letters Patent and mak-lng 'part of the sax-ne.

Beit known'that I, CHARLES CARR, of Boston, in the county 'of Suiolk, and State of Massachusetts, have inventedcertain new and useful Improvements to be a full, clear, and exact4 description of the con- ,struction and operationof the same, reference being hdto the drawing, forming a part of this sp'ecical tion, of whichl Figure 1 is a side elevation.

Figure 2is -a plan, showing the reversing-dogsz 2,* also, -representing the reversingarm f and lever s.

Figure 3fis atransverse section on line A B, representing thespiral groove fr, by which the motion. is communicated to the friction b.

g is the hollow pulley-shaft, on which is keyed the driving-pinionv, and which carries the friction b, the saine having a lateral motion on the spline n.

a, a are pulleys', running loose on the hollow shaft' c c are nuts, screwed on the shaft g, to adjust the pulleys a a to the friction b.

d d are collars, which hold the pulleys back in their proper positions.

i isa key, which secures the friction b to the rod h.

e e are clasps, lugs, or studs, secured to the shaft g, to carry, andalso act as fulcra for ingersjjyl j.

'm is a sliding collar, which is connected 'with the links k k k k, whichgive motion to the iingersjjjj. Y p p are slots, through the hollow shaft g and rod h.

s is a lever, hanging at l, the lower end being formed the top carrying the ball x.

g y is a connnection between the lever s and the reverst is a rod, `through which the motion is conveyed' from the lever s to the sliding collar m by the yoke w.

In operating, when the lever s and arm f are central, the planer is at rest. By moving either for s,

the' lever s passes the centre, causing the spiralto rotate, which moves the rod laterally to the planer, car-- rying', .with'the yoke w, the sliding collar m.

The @011er m, in Sliding, throws the links k k k k at' -one end in avertical, and at the other end in aninclined position as toggle-j oints. In doing so, the inner ends of the fingers j jjj are movedn an opposite direction to collar m, and carrying with them the rod h., which forces the friction l in contact with'the pulleys a a. 'Y

The advantages gained lby'this invention:

First, the belts, one open andone crossed, continue to' run on the same pulley, and are not moved from side to side, as in the usual way, therebyavoiding the C lai/ms.

l. I claim the combination of hollow shaft g, rod h, lingers j j, and studs e e, all constructed and arranged substantially as described, for the purpose of actuating the clutch b.

2. I also claim the combination of `hollow shait g, rod h, clutch b, and pulleys a a, all arranged and operating substantially as set forth.

3. I also claim the combination of lever s, spiralv groove r, rod t, and yoke w, all arranged and operating toreciprocate the rod h, in the manner specified.

4. I also claim the combination ofthe subject-matter of the second and third clauses, arranged to operate in the manner and forrthe purpose substantially as CHARLES GARR.

' set forth.
